Policy is guidance only — providers must use professional judgment
This clinical policy does not constitute medical advice or a guarantee of coverage; providers must exercise professional medical judgment when diagnosing and treating members and remain responsible for all medical advice and treatment decisions.
- Providers are independent contractors and not agents or employees of the Health Plan.
- The policy is not intended to dictate clinical practice or recommend treatment.
Document clinical justification and accept responsibility for treatment
Provide sufficient clinical documentation to support medical necessity when requesting coverage or submitting claims; the clinical policy is a guide and does not guarantee payment or results.
- Providers are expected to exercise professional medical judgment and remain responsible for medical advice and treatment of members.
- Coverage decisions and administration of benefits remain subject to the terms, conditions, exclusions and limitations of the member's coverage documents.
Follow coverage documents; state Medicaid provisions prevail when they conflict
Coverage decisions and administration of benefits are governed by the member's coverage documents and applicable law; if state Medicaid coverage provisions conflict with this clinical policy, the state Medicaid provisions take precedence.
- Refer to the member's evidence of coverage, certificate of coverage, policy or contract for specific terms, exclusions, and limitations.
- For Medicaid members, consult the state Medicaid manual for controlling coverage provisions.
Background
Orthognathic surgery encompasses surgical procedures to correct dentofacial and jaw deformities and is described in standard specialty texts and the peer‑reviewed literature cited in this policy. The policy was developed by clinicians experienced in this area and is informed by contemporary advances such as three‑dimensional surgical planning and simulation, which have improved operative precision and outcomes in orthognathic procedures.
Recent systematic reviews and specialty references support that orthognathic surgery indications, techniques, and outcomes are well‑documented; this policy aligns with that body of evidence and with accepted standards of care at the time of approval. As noted elsewhere in this policy, it is intended as a guide to medical necessity and does not replace professional medical judgment or applicable legal and regulatory requirements.

OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.
